1 Be it known that l, JAMES R. HUGHES, of

` Saugus, in the county Massachusetts, have invented certain new and y i useful Improvements y lwhich the following, taken in connection with the accompanying drawings,is a specification.

of Essex and State of in" Nutmeg-Graters, of

My invention relates to that class of graters in whichthe grating-surface is formed upon the periphery of a cylinder adapted to revolve past the side` of the nutmeg, -`successive actionofits teeth thereon reduce it 1 `fr have found that in the use of suen @yunf ders as heretofore constructed, with the teeth in regular rows and the article to" be grated held in a fixed position, the teeth of the cylindercut grooves into the cle in parallel lines, leaving a ,ridge between each two of saidlgrooves, which bears against g @the smooth portion of the cylinders,andthere byretards the feeding of the nutmeg, and renders the process of should otherwise be.

grating slower than 4it `Toiobviate this objection is the object of a my present invention, which resultsin apply y ling to the grating-cylinder, in addition to its A 1 rotary motion, a short reciprocatingmotion in thedirection of the length of its axis, so as 1 to break up` the continuous cutting of the "teeth inthe same ruts. f This I accomplish by making the cylinder` somewhat longer than usual, and

`oniits periphery, nearoneend and outside of i the supportingc'asing,

, cam-path, which extends entirely aroundsaid y ycylinder, and engages with` a fixedpin secured tothe side of thesupporting-casing, as will'be .a y hereinafter described.` y A V My invention further consists in so cony structin g the interior of the supporting-casing thatthe upper side of `that portion of the interior of said casing which is in the rear of thecylinder, and in which is placed ,the nut y meg or other, article to `be grated, and the foli lower which y cylinder, shall be somewhat belowthe extreme upper side of the cylinder, so as (to render the l y angle formed between said upper interiorsurforming upa serpentine groove or presses said article against the face and the rear portion of the periphery'of a `the cylinder comparativelyObtuse," the object and by constant and nutmeg or `other arti-` `of which construction is to prevent the nuty meg being ground away to a thin, sharp wedge form, and then broken off in lumps by the action of the grating-cylinder, as would be the case were the upper side of said `casing con- :structed likethe lower side, it being understood that the cylinderis to be revolved in the direction indicated by the arrow. -Figure 1 of the drawings is a plan of my improved grater.

A is thesupporting-casing,made preferably a in the form of a rectangular tube, and closed at one end by the handle B,and having mount-` ed in suitable bearings in` its other,l end the gratingcylinder O, arranged withits axis extending transversely across said casing, with. its endsprojecting beyondythe walls of the `casing A, and providedat one end with the y i y crank .D, by which it `may be revolved, and at l i,

the othersendwith the serpentine camgroove a, extending entirely around its shownin Figs. 1 and 4. y

` Al is a partition, placed inthe upper part of casing A to contract its area in the rear of the cylinder, to prevent the article being grated from being wedgedinto an acute angle by the revolutions of the cylinderin the direction of the arrow. The same result may be produced by making the casing A smallerinthe rear` of the cylinder on its` upper side, or to conform tothe shape ofthe partition-plate A a without the outside plate at that part.

E is the follower, placed inthecasing A between the cylinder C and handleB, and providedwith `a roughened surface, b, at its front c end, to'engage with the nutmeg or other artif# pin c, projecting upward therefrom through the slot d in `the cle to be grated, and with the casingA, to theupper end of which pin` one end of the spring e isremovably connected,

the opposite end of said spring being secured to the front end of thecasing A. i

@The casing A has formed isisupplied to the grater, and upon its site side has secured thereto the pin g,ythe

outer end of which enters the cam-groove a., in such a manner that as the cyllnder C 1s -ref dated December 25, 1877; `application iiled u Fig. 2 is a sideelevation. `Fig` 3 is an elevation of the opposite side. Fig. L is an end view, and Fig. 5 allongitudiy periphery, as

in its right-hand side the opening f, through which the nutmeg y oppo-` vvolved about its axis the serpentine or cam-` der having a grating-surface upon'tlecentralf portion of its periphery, and mounted land adapted to revolve in bearings outside of said grating-surface, and-a device for imparting toi said Y cylinder a reciprocating motion, substan tially-fas and'for tle purposes described 2L In combination With arevolving gratingcylinder, the holder-tube A, arranged with its center line atr one side of or eccentrically to i the plane of the axis of the cylinder, substantiallyas and for the purposes described.

Executed at Boston, Massachusetts, this `11th day of October,lA. D. 1877.
